9. Export the environment variable that specifies the Raid Manager
instance to be used by the Raid Manager commands. For example,
with the POSIX shell type:
# export HORCMINST=0
Now, you can use Raid Manager commands to get further
information from the disk arrays.
To verify the software revision of the Raid Manager and the
firmware revision of the XP disk array, use the command:
# raidqry -l
NOTE Ensure that you have the minimum requirement level for the XP and
the Raid Manager software and firmware listed in the
ContinentalClusters release notes.
To get a list of the available devices on the disk arrays, use the
command
# raidscan
This command must be invoked separately for each host interface
connection to the disk array. For example, if there are two Fibre
Channel host adapters, you might use the commands:
# raidscan -p CL1-A
# raidscan -p CL1-B
NOTE There must also be alternate links for each device, and these
alternate links must be on different busses inside the XP disk array.
These alternate links, for example, may be CL2-E and CL2-F.
Unless the devices have been previously paired either on this or
another host, the devices will show up as SMPL (simplex). Paired
devices will show up as PVOL (primary volume) or SVOL (secondary
volume).
10. Determine which devices will be used by the application package.
Define a device group that contains all of these devices. It is
recommended that you use a name that is easily associated with the
